Edit: Could you describe in more detail where the Rylak Roost is? I've traveled around Grom'gar but I've only run across flying Rylak, and none that are nesting.

Edit #2: I finally found the nests and the "Wiggling Egg" that dropped a Mysterious Egg. We'll see what pops out after the three days is up.

I have to wonder, though, what a tropical bird is doing in a cold environment like Frost Fire Ridge lol. Finding the Fruit Hunter seems a little odd to me. Unless all the Draenor "egg" pets can come from any egg, regardless of which zone the egg was looted from. We'll see.

Another concern: Is a pet guaranteed from the egg after three days? If not, that could be irritating. Treasure containers (such as the Wiggling egg) seem to only be lootable once per toon. This means if RNG plays a part in what drops we might need multiple characters to loot it just for a chance at whatever pet is inside.
